[Q] Forgot to flash the kernel before installing ICS beta rom with xperia arc

Hi all,
My phone is rooted and has an unlocked bootloader, but I tried to install this rom today:
MooDeD ICS ROM v.4.0 / xUltimate v7.0 Engine [ROM]
http://forum.xda-developers.com/showthread.php?t=1526717
But I forgot to flash the new boot.img (new kernel), wich I had to install using flashtool. Now I can't normally boot my Arc (I can understand why), but I also can't get into CWM recovery! So do I know have to flash the new kernel wich I had to do before.. or can I get Android 2.3.4 somehow back on my Arc? And if I flash the new kernel for ICS can I flash it back to the kernel for Gingerbread afterwarts? The new kernel is based on ICS beta btw.
I hope you can help me
Everything is working very well since I flashed the ICS kernel I am now running Mooded ICS rom v30.5 without any problems (few bugs in the rom, but overcomable)

I figured that flashing ICS kernel and install the rom again worked when I had flashed the kernel I could get back into recovery again Thanks for your reply

does the DoomLord Kernel work on a ICS rom? Or does it has to be the ICS kernell by DoomLord?! on other words on ICS Roms the kernel has also to be based on ICS?

That's correct as far as I know has to be ics

I don't recommend doomlord because it's a bit buggy, but there are plenty of usefull kernells. To make ICS work you will need ICS kernell

[Q] Can I flash a different kernel with a custom ROM?

Is it possible to, or should I flash a different Kernel onto a custom ROM? Will it break my phone? I wanted to check out the JB Camera in the SSGSII Themes and Apps forum. But it says you have to have a CM10 kernel. I am running Darkside evolution v8. I am not all up to speed on how kernels work or how they relate as far as compatability issue. Thanks for the help and feedback !

Yes you can.but make sure the kernel is for TW ROM.
Ps.i have tried couples different kernels and the darkside v3 is the best one.(my opinion)

[Q] How do I get stock kernel back?

How can I get my stock kernel back? Or does flashing a ROM change the kernel? I don't really understand kernels yet in terms of compatibility, and such. I just don't want to brick my phone, so I'm making sure I do it right.

Roms usually involve a kernel already built in, check the OP description.
For example if you are on cm10 and flash the ktoonsez aosp kernel, then later flash a nightlie build, the kernel will be overwritten with the one built in cm10. You have to reflash the ktoonsez again afterwards if you want to use it.
So if you want stock kernel, flash a stock ROM with built in stock kernel.

Make sure the kernel you flash is sourced from the same source as your ROM, ie any TouchWiz LG8 ROM needs to have an LG8-sourced kernel - custom or stock.

[Q] stock ICS

hi I have unlocked the bootloader of my xperia arc now if I would try the Serene Kernel -> http://forum.xda-developers.com/showthread.php?t=2097138 in the post says I should use the official rom, as I put it with the bootloader unlocked?

Well well well, if you got a stockbased rom, then try it

I am now using the cyanogen 10, so I changed the kernel on the phone, the fact is that I do not know which ROM install after putting the kernel, I also wondered if it would be compatible with cyanogen 9 of Anzu.

ICS kernels will only work with ICS ROMs
JB kernels will only work with JB ROMs
GB kernels will only work with GB ROMs
stock based kernels are compatible with stock based ROMs only.
most (NOT ALL) non stock based kernels are compatible with any cm/Aokp/miui ROMs
so to answer your Q: serene kernel will not work on CM10 because
1) former is for ICS but CM10 is jb
2) cm10 is a non stock based ROM is

Try out different kernels to see what you like, but be sure that the ROM matches the KERNEL! or it won't boot!

I already know, in fact wondering where I can find the official ROM for bootloader unlocked so as to put the kernel serene.

[q] help with cm 10.1 kernel

I recently flashed CM10.1 on my ATT Galaxy Note II and like a moron attempted to flash a different kernel. I just need someone to direct me to where I can get a COMPATIBLE kernel for my device on CM10.1 the stock 10.1 kernel or any others that are better or will work etc. Thanks.

Either reflash the rom, or find a kernel in the original development section that says it's for an aosp rom, not a touch wiz rom!
